leaving small town FD for a big city FD in another state

How many of you have left a small town FD to go to work for a big city FD? I have recently been hired by one of the 10 largest FDs in the US and am curious how many of you have made a similar move? I have been in a small paid department (80 FF/4 stations) for a bit over 7 years. I am number three on the captain's list. The money is almost the same (after you factor in the cost of living) and put the two FDs/cities on a level "playing field). Please tell me your experiences.
